INSTALLATION
The Heat Wagon Model 1800(SL) is a direct fired gas heater intended to be used primarily for the
temporary heating of building under construction, alteration, or repair. Since all the products of
combustion are released into the area being heated, it is imperative that adequate ventilation is pro-
vided. The flow of supply air and combustion gases must not be obstructed in any way.
1. The heater is designed for indoor or outdoor installation in a horizontal position. Allow the
following clearances from any combustible material or fuel containers.
Front Outlet:
10 feet
Sides:
2 feet
Intake:
1.5 feet
Top:
4 feet
Also make sure that no flammable vapors are present in the space where the heaters is being used.
2. The heater should be inspected before each use, and at least annually by a qualified service
person.
3. The hose assembly must be inspected prior to each use of the heater. If it is evident that there is
excessive abrasion or wear, or the hose is cut, it must be replaced prior to the heater being put
into operation. The replacement hose assembly shall be that specified by the manufacturer.
See parts list.
4. When connecting the heater to a natural gas or propane supply line ensure that the pressure at
the heater inlet is within the specified range. Excessive pressure (over 50 psig) will damage the
controls and void the warranty.
5. Connect the hose assembly to the heater gas inlet elbow. The 1800 elbow has 3/4” Female NPT
thread, 1800SL elbow has a 1/4” Female NPT thread. The hose assembly is supplied with a
swivel connector to avoid kinking or twisting the hose. Use a minimum inside diameter of 1/2”
on LP or 3/4” on natural gas installations. Ensure that the hose assembly is protected from
traffic, building materials, and contact with hot surfaces.
6. After installation, check hose assembly for gas leaks by applying a soap and water solution to
each connection.
7. Connect the heater to an adequate 115 volt electrical supply as specified on the rating plate. For
protection against shock hazard the supply cord should be plugged directly into a properly
grounded three-prong receptacle.
8. Replacement parts are available from any Heat Wagon distributor or by calling 1-888-432-8924
